Abstract: PURPOSE:To eliminate fluctuations in driving a bed furnished with driving mechanisms in X and Ydirections, by supporting one end of a supporting body incorporating an X-direction rail by one pivot and the other end by two pivots so that a difference in displacement amount between left and right receiving bases can be absorbed. CONSTITUTION:A chip part suction mounting head 20 for mounting chip parts onto a board is installed on an X-direction rail 21, which is laid on a supporting body 22 whose left end is supported by a receiving base 23 through a receiving saddle 32 and whose right end is supported by a receiving base 24 through the receiving saddle 32. Each of the receiving bases 23 and 24 is supported by a Y-direction rail 26 and 27 respectively, while each of the receiving saddles 30 and 32 is axially mounted onto one end part of a link 31 and onto the receiving base 24 through pivots 33 and 34. The other end part of the link 31 is axially mounted onto the receiving base 23. Consequently, when the receiving bases 23 and 24 are displaced by different amounts, the difference is absorbed by the rotation of the receiving saddle 30 and the link 31 around the pivots 33 and 35, and by the rotation of the receiving saddle 32 around the pivot 34.

Abstract: PURPOSE: To obtain a multilayer printed board in which the core expands/ contacts similarly to the cavity part at the time of temperature rise or fall during a heating operation by employing a jig made of the same material as that of an intermediate layer or a thermosetting resin. CONSTITUTION: A dummy 22 corresponding to a multilayer printed board 1 forms a part 23 having an intermediate layer formed with the same circuit as that of the multilayer printed board 1 and corresponding to a cavity part 2. A heat resistant sheet 24 is formed of acryl based material as mold releasing material for a core 20 and the multilayer printed board 1. A modified polyimide prepreg 25 is employed as material for forming a protrusion of the core 20. With such arrangement, the modified polyimide prepreg 25 is heated by upper and lower dies 21 according to a recommended lamination temperature profile thus forming the core 20. Since the core 20 is made of material equivalent to that of the multilayer printed board 1, the core 20 and the multilayer printed board 1 behave similarly at the time of temperature profile.  Consequently, the core 20 expands/contracts similarly to the cavity part.

Abstract: PURPOSE:To improve the pressure raising effect by controlling linearly a rotation phase converting means with two oil pressure control valves which are duty-controlled, so as to set the valve opening and closing timing at an optimum condition constantly, and operating the discharge pressure of the second hydraulic pump to the rotation phase converting means. CONSTITUTION:An electronic control device 12 calculates the control object value of a camshaft 14 depending on the operation condition of an engine 11. And the valve opening and closing timing at the present condition is detected by the output signals of a crank position sensor 15 and a cam position sensor 16, and it is compared with the control object value to determine the rotation phase converting amount of the camshaft 14. Furthermore, the electronic control device 12 controls the first and the second oil pressure control valves 24 and 25. When the valve opening and closing timing is advanced from the present condition, for example, the first oil pressure control valve 24 is controlled after the second oil pressure control valve 25 is fully closed. As a result, a high pressure oil discharged from the second hydraulic pump 22 is fed to an operation line 28, and the pressure operates to an oil pressure chamber 37. Consequently, a ring-form piston 31 is moved to convert the rotation phase of a timing pulley 30 and the camshaft 14.
